Hey, I don't know the details of your situation, Unleashed, so I can only offer some general advice base on my past experiences.
Also, I ain't Dr. Phil, so don't accept this as professional advice.
Don't start 'dating' (as much as the other guys on this site may object

)...
1) You need to recooperate from 10 years of routine and habits. As much as Mister Unleashed was a royale you-know-what, he was a major part of your life and you don't need to rush out and immediately 'fill the void' (in every sense of the word). Don't worry, your biological clock isn't going to go off. Now is the time to 'find yourself' and not in the local nightclub either. What you are doing with friends in your area is a great first step.
2) Take time for your children. Plan time for the kids... you guys are the family now and you need to 'get closer'. (At the very least, they may clean up their room without you yelling as much if you spend time with them

) Don't be like one woman who wanted to go out with me and try to 'pawn them off' on the first person who came along so she could have the weekend free... it makes your kids feel like crap and unwanted, too.
WHEN you
do get around to dating new guys (and not that ESPN person) DON'T TALK Constantly about the former Mister Unleashed. The dude
you've chosen to go out is far more interested in YOU, not him. If the relationship grows (and not in THAT way), then you can start filling in the history.
You can check into the 'parents without partners'... again, I don't know how things are down there.... but around here, most of the 'parents without partners were 65 and exchanging dentures with each other.
I don't know if that helps, but hey! I'm loaded with advice...take what you can use and leave the rest!!!!
